Merging the publish-subscribe pattern with the shared memory paradigm

Abstract

Heterogeneous distributed architectures require high-level abstractions to ease the programmability and efficiently manage resources. Both the publish-subscribe and the shared memory models offer such abstraction. However they are intended to be used in different application contexts. In this paper we propose to merge these two models into a new one. It benefits from the rigorous cache coherence management of the shared memory and the ability to cope with dynamic large-scale environment of the publish-subscribe model. The publish-subscribe mechanisms have been implemented within a distributed shared memory system and tested using an heterogeneous micro-server.
